Seyfried was wooed by Channing Tatum in "Dear John" and locks lips with Justin Timberlake in the upcoming "Now," and the actress admits she enjoyed her on-screen smooches. "I can't lie," she says. "It didn’t suck making out with Channing and Justin."

But the actor she's had the most chemistry with is "Mamma Mia!" co-star Dominic Cooper. "[It is] one of the easiest things in the world," she says of falling in love on set. "You're both open. You’re put in a situation where you have to make out with each other. It's easy for things to get carried away."

And Seyfried did indeed get carried away, believing the British actor was breaking up with his longtime girlfriend to be with her.

"I was just kind of foolishly thinking that the two of them were done and Dom and I were involved. But we weren't really as involved as I thought," she says. "So I got my heart broken pretty hard."

Seyfried has also enjoyed a fling with "True Blood" star Alexander Skarsgard ("He's superfunny, but I was too involved with Dom," she explains), and more recently has been linked to Ryan Phillippe — although she plays coy when asked about the actor.

Despite being paired up with some of Hollywood's hottest hunks, there's still one actor who remains on Seyfried's wish list. "I'd really love to make out with Michael Fassbender," she says of the "X-Men: First Class" star. "Put me in a movie with that guy. I'm serious. Wow."

I saw her on Regis and Kelly today and love her interviews. She really is stunning, she reminds me of Michelle Pfieffer a little bit. I hope she has a very long career. Jennifer's Body is a guilty pleasure to watch as well- I'd love to see her in more campy roles like that!

some of you must be 12 or younger with the silly things you say. Still, she did come off as some easy floosy, I doubt any guy would date her seriously and allow her to go off to make a movie. Do you really have to fall in love with everyone you kiss on screen girlfriend?

There had to have been signs that she either didn't see or (more likely) chose to ignore. She had to have known to some extent that Dominic wasn't going to leave the woman he'd been with for so many years for her regardless of how much he told her "i love you".

It has been known to happen that the jerky guy that you're cheating with does leave his significant other. LeeAnn Rhimes and Eddie. Tori Spelling and Dean. Ladies - quit stealing other women's men! All parties involved are less than moral.
